New Overview for all TFS Migration / Integration Tools

I assume most of our major enterprise customers are not all-Microsoft shops and/or are not running all-MS tools. Our goal is to make developers successful with the very best tools, not to lock them all to our tools. (Of course I want our tools to be the very best, :) but it’s important to meet customers where they are and give them flexibility.) Most large enterprise customers ask, “can I get some help migrating my existing tool X to TFS?” Another very common one is “I have another branch/department/… using another tool – is there a good way we can work together?
